Safety model
Pharos warns. It does not approve.
The app is educational decision support. It surfaces documented interaction warnings so a user can talk to a pharmacist or clinician. It does not diagnose, prescribe, dose, or tell a user to start or stop medicine.
Never says
“This is safe for you.”
No documented interaction found is not a medical clearance. It only means Pharos did not retrieve a matching DDInter pair.
Always says
Confirm with a professional
Warnings are framed as reasons to speak with a pharmacist or doctor, not as treatment instructions.
When unsure
Abstain, do not invent
If the drug cannot be resolved or the OCR confidence is too low, Pharos refuses to fabricate a conclusion.
Privacy boundary
The shelf belongs to the device.
- The medication shelf is stored locally on the phone.
- Inference does not rely on a remote medical API.
- The app can explain the retrieved fact without exposing medication history to a web service.
- Mesh delegation, when used, is explicit and bounded to the explanation step.
Safety wording
Designed to warn, not prescribe.
Pharos keeps the medical boundary visible in the UI: it surfaces documented interaction risk, then directs users to a pharmacist or doctor for decisions.
Educational information only. Pharos does not diagnose, dose, prescribe, or tell you to start or stop a medication. Always confirm decisions with a pharmacist or doctor.
